Abstract: Suppose p<qare odd and relatively prime. In this paper we complete the proof that K n,n has a factorisation into factors F whose components are copies of K p,q if and only if n is a multiple of pq(p+q). The final step is to solve the "c-value problem" of Martin. This is accomplished by proving the following fact and some variants: For any 0 n, there exists a sequence (# 1 ,# 2 ,...,# 2k+1 ) of (not necessarily distinct) permutations of {1, 2,...,n} such that each value in {-k,1 -...
